Types of Mold Release agents
Mold Release Agent is a water-based or solvent-based coating that prevents material from bonding to the surfaces of a mold. This process is used to make plastic, rubber, and metal parts for all sorts of industries.
There are several types of release agents available to suit different needs and applications. Sacrificial (typically waxes and oils) and PVA release agents are the least expensive, offer adequate slip and chemical inertness, but require re-application after each molding cycle. They are also more susceptible to transferring onto the mold part and requiring post-operation cleaning, which can reduce production output.
Semi-Permanent releases do not require re-application and are usually more effective as they are applied less frequently. They also reduce forming time by preventing sticking and cracking.
PTFE Fluoropolymer Dry Film Release
A wide range of PTFE and fluoropolymer solutions that produce thin, dryfilms on the mold surface. These formulations are chemically inert, non-migrating, and do not stain. They are ideal for rubber-to-metal bonding operations and when molders are molding silicone elastomers.
Whether you’re manufacturing food-grade plastics, wax, or rubber, provides the ultimate mold release solution. This non-staining, non-corrosive formula is highly effective at low and high mold temperatures.
There are many ways to get mold releases, but the most effective way is through a release spray. These can be used to coat large, flat surfaces or even smaller details that can be difficult to apply with a cloth.
